To all whom it may concern.-

Be it known that I, FRANoors CHAPSAL, a

citizen of the Republic of France, residing at the city. of Paris, France, have invented certain new and useful Improvements inFeed- \Vater Purifiers, (patented in France December 7, 1889, No. 202,446,) and I do hereby declare the following to be a full, clear, and exact description of the same. The apparatus forming the subject of my invention is composed of an auxiliary reservolr fixed on or connected with the generators of steam and is especially adapted to locomotive-boilers. The feed-wateris heated in passing through the reservoir or decanter having a circulation of steam, where it deposits the salts or other impurities precipitated by the heat. The purification of the feed-water is completed by its passage 'through a filter. The feed-water forced by the pump or by the injector is fed either directly to the decanter by one or more tubes connected between themselves in the interior or on the exterior to the generator, or by any heating apparatus placed in or outside of the boiler.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical section through my improved feed-Water purifier. Figs. 2 and 3 are horizontal sections through the purifier. Fig. 2 is a section through A B, and Fig. 3 a section through 0 D. Fig. 4 is an enlarged section of a part of the purifier, showing details of construction.

The decantation apparatus consists of a series of cones N,within which there is a steamoirculation, mounted on a tube t,which forms the center and which is in communication with the steam-space of the boiler. The water resulting from the condensation of the steam in these cones drops into tubetthrough the openings P and returns to the boiler. The feed-water comes by a tube placed in themterior of the boiler. The water thus introduced mounts in the apparatus while circulating, as indicated by t-he arrows in Fig. 1, around the cones N, in which steam circulates. It-is seen by these arrows that the water is forced to be in prolonged contact with the heating-cones N. Above these cones are diaphragms S, on which is collected the sediment which the water leaves while heating.

These diaphragms areinclinedin such a manner that the deposits gravitate toward their outer edges 0, which are in contact with the interior casing E of the purifying apparatus. The sediment as it accumulates passes through openings 0 into the angular space between the interior casing Eeiiidthe exterior casing R, forming a collectorof the sediment. The sediment thus isolated between. the casingsE and B, Fig. 1, can be drawn oif bya cook and drain-pipe V, for the upper part of the annular space being closed no circulation of water can establish itself in the collector of sediments and these impurities will fall to the bottom. The water as it passes upward through the purifier is heated more and more by its continued contact with the cones in which the steam circulates, and its purification becomes in consequence more and more perfect. IVhen it has arrived at X X, Fig. 1,it must traversea filter X XYY, formed of two diaphragms, between which are fragments of coke, sand, and any other filtering matter. WVater then passes to the upper part of the reservoir, and it flows through a special tube 15, mounted in the interior of the first tube. A small tube 25, des-. tined to assure the communication of the steam with the upper part of the dome, is fixed in the tube 15. This tube 25 maintains the equilibrium of pressu rein the whole purifying apparatus. The water traverses the exterior of these diaphragm-cones, passing through sleeves U, and is forced to circulate around the cones. In this manner the join ing of the groups of the cones can be made of bolts fixed on the inner lugs of the flange and by nuts tightened on the bolts by means of a wrench. The central tube,by which the purified water flows into the boiler, is put in its place the last and is joined by means of bolts and nuts on the outer flange of the last group of cones. It has the object of allowing the heating-cones to be put in place and dismounted without entering the boiler. This mounting is not claimed and may be varied at will.

lVhat I claim is 1. In a feed-water purifier, the combination, with the tube 25, communicating with the steam-space of the boiler, and the series of in the interior of each piece of pipe by means ICO cones mounted thereon, of diaphragms S for collecting the sediment from the heated water, substantially as set forth.

2. 1n afeed-waterpnrifier, the combination, substantially as described, of the outer shell having a closed top provided at its lower end with adisoharge-opening, the inner shell provided at bottom with an inlet and at intervals of its length with openings, a filter (one or more) arranged at the top of the inner shell and closing the top of the annular space between the shells, a pipe extending from above the filter through the inn er she1l,-hollow steam-
